While preparing to share this post on LinkedIn, I noticed something’s missing.
The preview didn’t show an image or description.
Apparently there’s a special so-called Open Graph protocol that solves this problem.

From the protocol’s introduction:

The Open Graph protocol enables any web page to become a
rich object in a social graph. For instance, this is used on Facebook to allow
any web page to have the same functionality as any other object on Facebook.

I got it working in ox-hugo by:

1. Adding opengraph = true in the [params] section of hugo’s config.toml
   
2. Adding this org property for the image: EXPORT_HUGO_CUSTOM_FRONT_MATTER
   
3. Adding this org block for description: begin_description
   

Long story short. Here’s the applied change for the beforementioned post. Shortened but still raw:

git show 2ce4aa9
